Weapon Masters of Techadon are a weapons and technology R&D group from Techadon. One of them first appeared in Inspector 13, but they were mentioned in earlier episodes. They are a weapons group that creates, supplies and sells weapons to anyone who can afford them their prices. They are incredibly anti-social and never leave their homeworld. No one has ever seen one of them and lived. It is even impossible to encounter the Weapon Masters when buying their products, as when Vulkanus bought Techadon battle robots from them, they simply sent a remote unit to construct them.
